Pneumatic Actuators

Double Acting & Spring Return Actuator

Features:Spring  Return Actuator

  • Two external travel stops permit adjustments of +/- 5 degree. Note : Travel stops are located on end caps on size 045 only.
  • Top quality bearings and seals form low friction and high cycle life to ensure trouble free operation. Same bearings are used for both high and low temperature operations.
  • Modular pre-loaded spring cartridges with metal spring guides for use in both high and low temperature applications.
  • Hard anodized extruded aluminum body with honed internal surface for strength, high cycle life, and low frictional resistance.
  • Unique output shaft insert can be selected from a variety of standard sizes, including double D, ISO square, and round and keyed, or can be custom designed to fit any output shaft configuration.
  • Standard end caps are rounded with no crevices to accumulate contamination. Optional end caps are available to provide 100% stroke adjustment in one direction.


Stainless Steel Pneumatic Actuator Series SSPA-10

Limit SwitchFeatures:

  • Body:  The all-SS housing is ideal for sanitary, pulp and paper, marine and a variety of other applications where corrosion-resistance is crucial.
  • Bearings:  Replacable top and bottom TFE pinion bearings ensure low friction, stability up to 400°F and corrosion resistance.
  • Heavy Duty Pinion:  The one-piece stainless steel alloy shaft has precision machined gear teeth for precise operations.
  • Mounting:  ISO 5211 standard design provides direct mounting of most ISO pad valves, including Valtorc valves.
  • Spring Cartridges: The heavy duty spring cartridges are designed for easy conversion of a double acting actuator to a spring return actuator, or to modify the torque output depending on air pressure.
